摘要： The present embodiments disclose a method of and device for identifying the direction of characters in an image block. The method includes: performing optical character recognition processing on the image block by assuming various directions as assumed character directions to obtain sub image blocks, recognized characters corresponding to the sub image blocks and correctness measures thereof in each assumed character directions; in sub image blocks in the assumed character directions with 180° mutual relation, searching for a minimum matching pair of the sub image blocks; adjusting the sub image blocks in the searched minimum matching pair to eliminate the effect, on an identification result, of different numbers of sub image blocks in various assumed character directions; calculating an accumulative correctness measure in each assumed character directions based on the adjusted sub image blocks; and identifying the direction of characters in the image block according to the accumulative correctness measures.

摘要： A multicast service method and apparatus for providing multicast service with various types of protections and recoveries. The method includes splitting a multicast service into a plurality of unidirectional point-to-point services from a source node to each sink node, where a signaling message of each unidirectional point-to-point services is independent of one another; establishing, at the source node which publishes the multicast service, one or more label switch paths for each unidirectional point-to-point service with the signaling messages; and receiving a notification message when a failure occurs in the network, where the notification message carries ID(s) of one or more label switch paths that are affected by the failure; establishing, by the source node, a recovered label switch path or a new backup label switch path in response to the notification message.

摘要： A system and method for secure communication is provided. A first hash-based message authentication code is generated from a shared secret and a first counter value stored in storage of a computing device. A second hash-based message authentication code is generated from such shared secret and a second counter value. An encryption key is derived from a function of the first hash-based message authentication code and the second hash-based message authentication code. A message is encrypted using the encryption key, and communicated via a network interface of the computing device.
